Very true tanking is not to hard at all with controller (i am also on PS4)
Healer is not overly bad but i do use macros for sch, whm i just cannot get used to on controller and astro is fine.
Also not sure if it was said, but hunt marks will also be useful for experience. There is a board at each Grand Companies HQ that you can pick them up.
I just do not recall if there was quests to unlock them or such, lol

Beast Tribes once you gain access to them (level 41) i highly suggest you start, and get the Sylph over and done with first (they are a pita)
